Incorrect IPv4 addresses are entered on the router interfaces.
RIPng is incompatible with dual-stack technology.
IPv4 is incompatible with RIPng.
Which statement accurately describes a characteristic of a security policy?
It creates a basis for legal action if necessary.
It should not need altering once it is implemented.
It provides step-by-step procedures to harden routers and other network devices.
It is kept private from users to prevent the possibility of circumvention of security measures.
Which characteristic of VPN technology prevents the contents of data communications from being read by unauthorized parties?
Refer to the exhibit. A network administrator is configuring Frame Relay on router HQ. It is desired that each Frame Relay PVC between the routers be in a separate subnet. Which two commands on HQ will accomplish this task for the connection to R1? (Choose two.)
HQ(config)# interface S0/0/0
HQ(config)# interface S0/0/0.1 multipoint
HQ(config)# interface S0/0/0.1 point-to-point
HQ(config-subif)# frame-relay interface dlci 103
HQ(config-subif)# frame-relay interface dlci 301
HQ(config-if)# frame-relay map ip 172.16.1.1 255.255.255.0 301 broadcast
Refer to the exhibit. Router1 and Router2 are directly connected over a point-to-point serial link. Router1 initiates a PPP session with Router2. Which statement is true based on the configuration?
The password is sent in clear text.
The routers are unable to authenticate.
The username and password are sent encrypted.
A hash value of the username and password are sent.
A technician has been asked to run Cisco SDM one-step lockdown on the router of a customer. What will be the result of this process?
Traffic is only forwarded from SDM-trusted Cisco routers.
Security testing is performed and the results are saved as a text file stored in NVRAM.
The router is tested for potential security problems and any necessary changes are made.
All traffic entering the router is quarantined and checked for viruses before being forwarded.
Which two statements are true about creating and applying access lists? (Choose two.)
There is an implicit deny at the end of all access lists.
One access list per port, per protocol, per direction is permitted.
Access list entries should filter in the order from general to specific.
The term "inbound" refers to traffic that enters the network from the router interface where the ACL is applied.
Standard ACLs should be applied closest to the source while extended ACLs should be applied closest to the destination.
Refer to the exhibit. Company ABC expanded its business and recently opened a new branch office in another country. IPv6 addresses have been used for the company network. The data servers Server1 and Server2 run applications which require end-to-end functionality, with unmodified packets that are forwarded from the source to the destination. The edge routers R1 and R2 support dual stack configuration. What solution should be deployed at the edge of the company network in order to successfully interconnect both offices?
a new WAN service supporting only IPv6
NAT overload to map inside IPv6 addresses to outside IPv4 address
a manually configured IPv6 tunnel between the edge routers R1 and R2
static NAT to map inside IPv6 addresses of the servers to an outside IPv4 address and dynamic NAT for the rest of the inside IPv6 addresses
A company uses a PVC with a committed information rate (CIR) of 128 kb/s and a committed burst information rate (CBIR) of 64 kb/s. The link is used to periodically send updates at a rate of 144 kb/s. What will happen to the update traffic?
The traffic will be sent, but the company will be charged a penalty.
The traffic will be sent using the additional CBIR and will be guaranteed delivery.
The traffic will be dropped at the CO for exceeding the committed information rate.
The traffic will be sent, but the burst traffic will be marked for discard if congestion is encountered.
Refer to the exhibit. All devices are configured as shown in the exhibit. PC1 is unable to ping the default gateway. What is the cause of the problem?
The default gateway is in the wrong subnet.
STP has blocked the port that PC1 is connected to.
Port Fa0/2 on S2 is assigned to the wrong VLAN.
S2 has the wrong IP address assigned to the VLAN30 interface.
A system administrator must provide Internet connectivity for ten hosts in a small remote office. The ISP has assigned two public IP addresses to this remote office. How can the system administrator configure the router to provide Internet access to all ten users at the same time?
Configure DHCP and static NAT.
Configure dynamic NAT for ten users.
Configure static NAT for all ten users.
Configure dynamic NAT with overload.
Refer to the exhibit. From the output of the show interfaces and ping commands, at which layer of the OSI model is a fault indicated?
Refer to the exhibit. Results of the show vlan and show vtp status commands for switches S1 and S2 are displayed in the exhibit. VLAN 11 was created on S1. Why is VLAN 11 missing from S2?
There is a Layer 2 loop.
The VTP domain names do not match.
Only one switch can be in server mode.
S2 has a higher spanning-tree priority for VLAN 11 than S1 does.
Refer to the exhibit. What is the effect of the extended ACL when applied inbound on the S0/0/0 interface on R2?
All IP traffic will be permitted during the specified days and time range.
Both IP and Telnet traffic will be permitted during the specified days and time range.
Only Telnet traffic destined for 172.16.10.0/24 will be permitted during the specified days and time range.
Telnet traffic will be permitted only during the specified days and time range. All other network traffic will be permitted any time.

Once a good password is created, do not change it.
Deliberately misspell words when creating passwords.
Create passwords that are at least 8 characters in length.
